COAL-GAS CONSUMER.

Application filed May 21,

This invention relates to devices for effecting the complete combustion of the gases given off by coal burning in a furnace and the principal object is to produce a device of this nature having means for superheating or preheating the air fed to the coal being burned, so that there may be a more ready and complete combining with the gases, thereby producing a maximum of heat with a minimum of waste.

Another object is to produce a. device of this nature in which the inrushing air may be baflied a great number of times by heating surfaces so as to effectually and evenly heat the air prior to introducing it into the furnace.

Other objects of the invention will be readily apparent upon reading the following description and claims. The description is to be read in conjunction with the accompanying drawing, in which:

Figure 1is a perspective view of a furnace provided with my improvement.

Figure 2is a horizontal sectional view of the device taken on the line 22 of Figure 4.

Figure 3is a section on line 3-3 of Figure 2.

Figure 4tis a section on line 1-4 of Figure 2.

Figure 5is a detail of the valve.

Figure 6is a detail end view of the valve structure illustrated in Figure 5.

Like characters of reference refer to like parts in all views.

Referring to the drawing in detail, 10 represents a furnace which may be of any suitable construction, having a door 11 and an outlet pipe 12. Pipe 12 is preferably provided with a damper 13, which for most satisfactory results, should be in closed position. All of these parts are old and wellknown.

The improvement per se consists of a wedge-shaped body 14 supported on the inner side of door 11 by an air inlet pipe or valve 15. The pipe 15 terminates outside of door 11 in an end web 16 having air aper- 1923. Serial No. 640,5 2.41.

tures 17 A turnable cap 18 provided with air apertures 19 controls the passage of air through the pipe 15 by bringing the elements 17 and 19 into or out of register.

The wedge-shaped body 14: is provided with a plurality of apertures or jets 20 in its pointed edge which is somewhat truncate to permit this. The base, or side adjacent the door 11 is provided with but a single aperture in which pipe 14 is threadedly engaged. Between these two walls are two partitions 21 and 22, the latter being nearer to the apertures 20, and being provided with two apertures 23 at each end of the partition and midway between the top and bottom thereof. Partition 21 has four apertures 24L, two of which are arranged near the ends of the partition and midway between the top and bottom, while the other two are placed in vertical alignment at the center of the partition.

Between the two partitions 21 and 22 are arranged a plurality of depending baffle plates 25 and upwardly extending intersperced baflie plates 26.

From the above it will be seen that the air passes through the valve or pipe 15 into the first large compartment indicated at 27, from which it passes through apertures 24 and is brought into contact with bafl les 25 and 26 before it passes out of apertures 23 to the jets 20 from which it is discharged in a heated condition into the gases rising from the coal.

What I claim is In a device of the class described, a substantially wedge-shaped body having a pair of transversely extending partitions therein in spaced relation and forming an inlet chamber, an outlet chamber and an intermediate chamber, said partitions being provided with openings, said openings being disposed in offset relation to provide a sinuous path through the body, and a plurality of staggeredly disposed baffle plates in said intermediate chamber.

In testimony whereof I affix my signature.
